There were some things that, as an agent, you were trained to do subconsciously. Admittedly, once he'd had enough alcohol, Oliver was a lot less able to do these things. But the night was still young, and he noted the comings and goings in the bar without having to think about it.

Until, of course, he noticed the young quartermaster touching his ear.

He only had to think back to know that the older man with him had come into the bar after he and the quartermaster had exchanged a few words. So when he stopped Q from leaving, that offered Athos an array of options. Not knowing whether the bar staff was involved narrowed them down, however.

He downed the rest of his glass, paid for it, then headed over to the two. "I'm ready for you now," he told Q, and gave the older gentleman a polite smile. "I'm afraid he and I had a prior engagement."
